CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the priority of Chinese patent application No. 201410454164.1 filed on Sep. 5, 2014, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to general-purpose chemical or physical laboratory equipment, in particular to an air shower system and a dressing room.

BACKGROUND

A clean room and an ultra clean room are widely used in an electronic workshop, a biological pharmacy laboratory, hospital operation room, chemical laboratory etc. The most important control indicator of the clean room is the cleanliness. To keep an excellent cleanliness is the most basic guarantee for the production and experiment in the clean room.

Generally, the dressing room is an only entrance for a relevant user to access the clean room and the relevant user is the largest pollution source in the clean room. Therefore, it is very important to control the cleanliness of the relevant user when the relevant user accesses the clean room through the dressing room. An air shower room of an air shower system is a necessary channel for the relevant user in the dressing room to access the clean room. An air shower effect of the relevant user passing through the air shower room will directly affect the cleanliness of the clean room.

In a traditional air shower room, air passes through a primary filter, and then is forced into a static pressure box by a centrifugal fan, and then passes through a high efficiency filter. After that, the air is forced into a small clean chamber, and then blown out at a high speed by nozzles on left and right sides to form a high-speed airflow which blows away the dust attached on the body of the relevant user and carried items. Then, the air with the dust is forced into the static pressure box through the small clean chamber, and repeats the above process.

In the above process, the air is blown out by the nozzle at a high speed which can be up to great than 20 m/s and a direction of the nozzle is fixed. If the air shower time is too long and the high-speed airflow is blown directly to the body of the relevant user, the relevant user feels uncomfortable. And the high-speed airflow is also blown directly to dust-free clothes, which causes fibers of dust-free clothes to be under a great impact force, which will destroy the fibrous tissue and reduce a service life of the dust-free clothe. When the relevant user accesses into clean rooms with different levels, the requirements are different accordingly. For example, when accessing into a clean room having an air cleaning level of more than 1000, a better air shower effect and a longer air shower time are needed.

When the relevant users make handover, large numbers of users gather in the dressing room. When they are changing clothes, a lot of clothing fiber fragments and dust pollution will be produced. As a result, the cleanliness degree in the dressing room is decreased and surfaces of dust-free clothes are polluted. Therefore, at this time, a better air shower effect is needed when the user passing through the air shower room. The traditional air shower system cannot recognize a real-time clean condition of the dressing room and cannot adjust the air shower effect according to the clean condition of the dressing room.

DETAILED DESCRIPTION

Embodiments of the present disclosure will be further described below in conjunction with the accompanying drawings and examples. The following embodiments are merely used to illustrate the present disclosure, but not intended to limit the scope of the present invention.

As shown in FIG. 1 and FIG. 3, an air shower system according to one embodiment of the present disclosure is provided within a dressing room according to one embodiment of the present disclosure.

An interior of the dressing room is divided into a dressing region 1 and an air shower region 2. An air shower room 20 of the air shower system is arranged in the air shower region 2, and a particle monitor 30 of the air shower system is arranged in the dressing region 1.

In one embodiment, the air shower system includes:

an air shower room 20, used for a user to pass therethrough, within which is provided a nozzle component 40 used for jetting air to the user;

a particle monitor 30, arranged outside the air shower room 20 and configured to detect concentration of particles in the air outside the air shower room 20;

a controller 10, connected with the nozzle component 40 and the particle monitor 30, respectively, and configured to control a working time of the nozzle component 40 according to the concentration of particles in the air outside the air shower room 20.

In the present disclosure, the air shower system can detect in real-time concentration of particles in the air outside the air shower room 20 by using the particle monitor 30, freely set a maximum limit value of the concentration of particles according to a cleaning level of a clean room where the user is going to enter and then flexibly control the working time of the nozzle component 40 according to the concentration of particles in the air outside the air shower room 20. For example, when large numbers of users gather in the dressing room and the concentration of the particles (dust) is high, the controller 10 controls the working time of the nozzle component 40 to extend the air shower time; and when the dressing room is cleaned and the cleanliness is in a good condition, the air shower time can be adjusted back to a normal value or correspondingly shortened so as to ensure the air shower effect.

As shown in FIG. 2, in the air shower system of the present disclosure, the nozzle component 40 may include:

a rotating body 50, which is arranged on a side wall of the air shower room 20, rotatable with respect to the side wall and includes a curved surface 51 protruding from the side wall;

a nozzle 60, which is arranged on the curved surface 51, connected to an air source, configured to jet air to the user, and able to rotate, when driven by the rotating body 50, in a range of 0-180 degree with respect to the side wall.

The controller 10 is connected to the nozzle 60 and configured to control the working time of the nozzle component 40 by controlling an opening and closing of the nozzle 60.

Alternatively, the nozzle component 40 may further include an electric motor 52. An output shaft of the electric motor 52 is connected with the rotating body 50 to drive the rotating body 50 to rotate. The electric motor 52 is arranged within a static pressure box 90.

In the air shower system according to the present disclosure, the electric motor 52 is arranged within the static pressure box of the air shower room. The electric motor 52 drives, through the rotating body 50, the nozzle 60 to rotate in a range of 0-180 degree with respect to the side wall. That is, during the working process, an angle between an axis of the nozzle 60 and a surface of the side wall may be in a range of 0-180. Therefore, an angle at which the nozzle 60 jets air to the user can be changed continuously, so that a better air shower effect can be achieved. As a result, the dust particles attached on dust-free clothes worn by the user can be removed completely by the air shower. Further, a damage made to the dust-free clothes by the high-speed airflow blown by the nozzle can be avoided and at the same time, user's discomfort caused by air blowing directly can be avoided.

In the air shower system, alternatively, the side wall may include a first vertical wall 21 and a second vertical wall 22; a channel 80 for the user to pass therethrough is formed by the first vertical wall 21 and the second vertical wall 22; a plurality of the nozzle components 40 is provided on the first vertical wall 2 land the second vertical wall 22 respectively; and each of the nozzles 60 of the nozzle components 40 on both the first vertical wall 21 and the second vertical wall 22 points to the channel 80 so as to jet air to the user in the channel 80.

Alternatively, the side wall may further include a top wall 23 connecting the first vertical wall 21 and the second vertical wall 22. The top wall 23 is arranged on top of the channel 80 and provided with a plurality of the nozzle components 40. Nozzles 60 of the nozzle components 40 on the top wall 23 point to the channel 80 so as to jet air to the user in the channel 80.

Alternatively, a plurality of grooves is provided in the first vertical wall 21, the second vertical wall 22 and the top wall 23, respectively. Each of the rotating bodies 50 of the plurality of the nozzle components 40 is arranged rotatably within a corresponding groove. Each curved surface 51 of the rotating bodies 50 of the plurality of the nozzle components 40 protrudes towards the channel 80.

In a traditional air shower room, the air shower time is fixed, and the nozzle is fixed and un-adjustable during the air shower process. However, in the air shower system according to the present disclosure, on one hand, the nozzle 60 is rotatable with respect to the side wall in a range of 0-180 degree so that the air shower effect is improved; and on the other hand, the air shower time can be adjusted automatically by the controller 10. Therefore, not only the problem of the user's discomfort caused by air blowing directly is solved, but also the problem that the air shower time cannot be adjusted automatically according to the pollution condition of the dressing room is solved.

Further, the air shower system may have a function of auto sensing and include an air shower room with a surrounding air shower. The air shower system can perform the air shower onto the user and goods carried by the user in a full range and dynamically and adjust the air shower time according to the cleanliness condition of the dressing room, so that a better air shower effect is achieved and the cleanliness of the clean room is ensured.

Specifically, the air shower system and the dressing room according to the present disclosure have the following advantages:

1. Excellent air shower effect: compared to the nozzles having fixed directions, by the nozzles which are rotatable when driven by the electric motor, a better air shower effect can be achieved, it is much easier to blow away the dust particles on the dust-free clothes worn by the user and the user feels more comfortable, so that the rejection of using the air shower by the user subjectively can be avoided. And the surround stereo air shower can also avoid the aging and fracture of fibers on the dust-free clothes due to high-speed airflow blowing directly.

2. Automatic adjustable air shower time: in the present disclosure, the air shower room is connected to the particle monitor which can sense and measure the particle concentration data in the dressing room at any time, when large numbers of user gather and change clothes, abundant fibrous debris accumulate, and then the concentration of particles in the dressing room will be increased. Therefore, particles on the surfaces of dust-free clothes stored in the dressing room will be increased. After the corresponding value is transmitted to the controller by the particle monitor, the controller will adjust the air shower time correspondingly according to the predetermined concentration values of particles, so as to ensure the air shower effect.

The above is only preferred embodiments of the present disclosure, it should be noted that several improvements and modifications may be made for a person skilled in the art without departing from the principle of the present disclosure, and also should be considered to fall within the protection scope of the present disclosure.
